Oil cooling seems to be a chronic problem, so I'm going to try to capture some of the better ideas on how to control oil temperatures as well as background data that can be useful along the way.
The oil lines running to the nose are 1/2" 3003 AL tubing, mated to Aeroquip #8 stainless steel braided and firesleeved hose in under the cowling. Some folks have reported good additional cooling by adding [NACA_VG_Installation|vortex generators] ahead of their cooling inlets.
As you can see from the series of pictures of Rene Dugas' airplane, he has a significant bump on the bottom of his Velocity that creates a low pressure zone and allows for good airflow through the cooler. He says that he can fly WOT at low altitude with good temperatures with this setup.
